MC!Deltafell is a Deltarune AU stylized after the popular AU Underfell, where all of the original good-natured characters are 'evil' and vise-versa. The AU (by then still simply called Deltafell) was created by deltaspooks on Tumblr just one day after the release of Deltarune.

Deltafell was canceled, but with a transfer of ownership to MrRadude (Wattpad)/AskPolveraSans (Tumblr),[2] it has become active again, and was later rebranded to MC!Deltafell. Only the new version of the story will be used as a reference for all the information in this article. MC!DeltaFell is distinguished from PK2018's[3] version of DeltaFell.

Trivia[]

  • MC!Deltafell doesn't actually make every character edgy, instead the AU mostly focuses on changing the personality of characters to be evil.
  • MC!Deltafell Sans is unchanged from his Underfell counterpart, much like the relationship between Undertale Sans and Deltarune Sans.
  • MC!Deltafell was a dead AU, until a transfer of ownership "revived" it.
